    Setting Audio Levels Introduction The RC-85 controller is the new “brain” of your repeater, but to have its orders carried out it needs a few connections. It needs to know when there’s a signal at the receiver’s input, and it needs to be able to tell the transmitter when to turn on and off.

  • Page 28: Carrier-Operated-Switch

    Contact the factory if you need help with your particular receiver. Since signals from different receivers can vary in characteristics, the RC-85 controller is designed to accept a variety of logic levels and to accept “high true”...

  • Page 29: Receiver Audio

    The receiver audio input circuitry to the RC-85 controller allows for a variety of signal levels and impedances. The audio input is capacitively coupled, which means that a dc level may be present on the signal supplied. The level is internally adjustable so that a fairly wide range of input levels is acceptable, but for best results the input audio should be .5 to 2.5 volts peak-to-peak.

  • Page 30: Telephone Line

    FCC Part 68 regulations. Power The RC-85 controller will operate from a supply voltage of 11.5 to 15 volts dc. Since the circuitry is primarily low power, high performance CMOS, its current requirements are less than about 200 mA. Low power single supply operation means it’s easy to battery backup, along with the rest of your repeater, to keep it...

  • Page 31: Wiring To Your Controller

    (see diagram below). Setting DIP Switch Options Switch settings on the RC-85 controller board select high or low true sense for the COS and PTT signals (see below). It’s now necessary to set the switches correctly to properly control the repeater.
  • Page 32 RC-85 Repeater Controller Owner’s Manual Remember that the RC-85 controller is an audio source to the transmitter, and its various audio levels should be balanced relative to each other. Do not confuse controller audio level adjustments with transmitter audio characteristics. The controller’s levels are best set using an oscilloscope at its audio output, or yes,...
  • Page 33 Touch-Tone Muting Noise and Kerchunker Filtering Introduction The RC-85 Repeater Controller brings your repeater to life by automatically controlling the operation of the system and by responding to Touch-Tone commands from its users. A system block diagram is shown below, illustrating how the controller fits into a typical repeater system.

  • Page 34: Command Channels

    RC-85 Repeater Controller Owner’s Manual The controller’s command decoder and command structure are described in detail in the next chapter. We’ll describe here the command channels, along with access modes, ID, courtesy tone, tail messages, and other aspects of the controller’s operation.

  • Page 35: Access

    ID Timing and Selection Amateur repeaters in the U.S. are required to ID at least every 10 minutes when in use. The RC-85 controller offers an intelligent ID algorithm which selects one of seven remotely programmable Morse code and synthesized speech ID messages based on the circumstances.

  • Page 36: Courtesy Tone

    RC-85 Repeater Controller Owner’s Manual ID Message” at the end of the repeater hang time. The Pending ID can rotate between three ID messages for variety. In addition, a “Special ID Message” can be added to the rotation for special events. The Pending and Special IDs can conveniently contain informational messages, as they occur, without interfering with conversations on the repeater.

  • Page 37: Tail Messages

    RC-85 Repeater Controller Owner’s Manual Tail Messages Up to three different tail messages may be programmed by the repeater owner and selected for use by the Control Operator. These messages are sent at the end of the hang time, just prior to dropping the transmitter carrier and can remind users of status of the machine of an approaching net or meeting.

  • Page 38: Touch-Tone Muting

    The Control Op may disable Touch-Tone muting so that all tones pass through the repeater. Noise and Kerchunker Filtering The RC-85 controller provides filtering against noise and kerchunking on the repeater receiver. An algorithm filters against spurious noise on the receiver COS logic input, preventing static crashes and random noise bursts from bringing up the repeater.
  • Page 39 Your controller speaks back to you in voice. Commands can be entered over the air, or over the phone, or over a control receiver. There are several levels of Touch-Tone commands which control the RC-85 controller. Your repeater group probably consists of three types of persons - the repeater owner or technical group, the Control Operators, and the general users.

  • Page 40: User Commands

    RC-85 Repeater Controller Owner’s Manual User Commands There are 13 classes of User commands, each with its own independent command code. User command codes consist of a prefix followed immediately by a command root. The prefix may be remotely programmed by the repeater owner using Configuration commands, while the command roots contain information related to the action desired.

  • Page 41: Configuration Commands

    RC-85 Repeater Controller Owner’s Manual stored in the controller’s non-volatile memory using a Configuration command. The Control Op Macro Sets make it easy to select a special mode, like night operation, or net mode. One easy to remember Control Op macrocommand can, in effect, perform many commands.

  • Page 42: Command Evaluation

    RC-85 Repeater Controller Owner’s Manual The classes of Configuration commands include: Messages Tone Parameters Courtesy Tone Selection Timers Command Code Prefixes Emergency Autodial Numbers Misc. Selections Command Evaluation The controller evaluates Touch-Tone commands to determine the function requested.

    RC-85 Repeater Controller Owner’s Manual Related Commands: Config Phone Hangup Message, Patch Hangup Command Control Op Control Op Onhook User Custom Hangup Code Patch Redial The phone number dialed is stored in a redial memory and is available for easy redial without the need to enter the entire phone number again.

  • Page 49: Selecting The Cover Tone For Semi-Private Patch

    RC-85 Repeater Controller Owner’s Manual Related Commands: Config Patch Utility Command Prefix Control Op Control Op Onhook Selecting the Cover Tone for Semi-private Patch The controller offers a “cover tone” available during patches which results in muting of the mobile audio through the repeater replaced by the cover tone. The cover tone offers a degree of privacy by allowing only one side of the conversation to be heard on the air (the telephone side).

  • Page 50: Loading And Erasing The User Loadable Autodialer

    RC-85 Repeater Controller Owner’s Manual Since the controller waits until the mobile is listening before the warning, the actual patch duration may end up being somewhat longer than the programmed patch timer plus 30 seconds. The timer may be extended over and over, but no warning is given before it times out again.

  • Page 51: Activating The User Loadable Autodialer

    RC-85 Repeater Controller Owner’s Manual Example: Autodial Bank 0 Load / Erase Prefix = 456 User sends “456 40”. Controller says, “Autodial Cancel” and erases location 40. Command: (User Autodial L/E Prefix) (Location) (Phone Number) or (User Autodial L/E Prefix) * (Location) (Phone Number)

  • Page 52: Activating The Emergency Autodialer

    RC-85 Repeater Controller Owner’s Manual You can inhibit the phone number readback by clicking the mike at the first pause. Waiting until the second pause allows you to verify the contents on the autodial memory. You can also prevent phone number readback of an autodial slot by having selected the “security”...

  • Page 53: Bringing Up The Reverse Patch From The Phone

    RC-85 Repeater Controller Owner’s Manual programmable messages, like “Operator”, “Fire”, “Police”, etc. These ten numbers are intended for emergency public service agencies, and the reponse indicates selection of the correct agency. The Emergency Autodialer does not require that the user click his mike to initiate telephone dialing. The patch is terminated just like the Autopatch and User Loadable Autodialer.

  • Page 54: Answering The Reverse Patch Over The Air

    RC-85 Repeater Controller Owner’s Manual Mode 2 causes the controller to ring out when a phone ring is detected, but the line is not answered until a repeater user enters the Reverse Patch Answer command over the air. A special Telephone Access Paging mode is described in Appendix III and applies when DIP switch 7 is on.

  • Page 55: Extending The Telephone Timer

    Reading Back Your Signal Strength Assuming that an S-meter signal voltage is connected to the RC-85 controller, users may interrogate their signal strength into the repeater. The controller always measures the S-meter one-half second into each new transmission and stores the reading.

  • Page 56: Commanding The Demo Messages And Bulletin Board

    RC-85 Repeater Controller Owner’s Manual Commanding the Demo Messages and Bulletin Board Users may call up several messages which may be programmed by the repeater owner to include information of interest to the users. They may also activate the various ID messages contained in the controller.
  • Page 57 RC-85 Repeater Controller Owner’s Manual The user may activate the link transmitter. Now repeater users are retransmitted over the link frequency and appear to listeners on the link frequency as any other user on that frequency. The link may be to other repeaters or to simplex frequencies.

  • Page 58: Unmuting Touch-Tone

    Unmuting Touch-Tone At times it is desirable to pass Touch-Tone sequences through the repeater or through to the phone line unmuted, without them being decoded by the RC-85 controller. For example, bringing up an autopatch on a repeater accessed through the remote base would require passing tones through the controller to the linked repeater.

  • Page 59: Taking The Touch-Tone Access Mode Up And Down

    RC-85 Repeater Controller Owner’s Manual Examples: Paging Prefix = xxx User sends xxxxx. Controller sends two tone sequential tones, A tone Group #2 Tone #3 (669.9 Hz), B tone Group #1 Tone #5 (433.7 Hz). User sends xxx. Controller sends eight second group call Group #3 Tone #6 (979.9 Hz).

  • Page 60: Activating The Spare Audio Function

    RC-85 Repeater Controller Owner’s Manual Hints: The controller sends the Forced CW ID Message when going down, if necessary, to properly ID at the end of an exchange of transmissions. When taken up, the Touch-Tone Access Mode Timer will take the repeater back down after a period of inactivity.
  • Page 61 RC-85 Repeater Controller Owner’s Manual Certain of the UF outputs take on dedicated functions when various options are selected. For example, UF 3 becomes a Phone Line Busy output when in the Phone Line Shared mode. UF commands to dedicated outputs are ignored by the controller.

  • Page 83 TS-32 may interface with the repeater receiver and the RC-85 controller (it is shown for PL decode only - the encode section may be used as you wish). The active high logic output (OUT-2) may drive the controller PL logic input (J3 pin 4) with a 10K pullup resistor to +12 volts.
  • Page 84 RC-85 Repeater Controller Owner’s Manual Audio into the TS-32 Tone Input should come from a point in the receiver where sub-audible tones have not been filtered out - the proper point is receiver dependent and in some cases audio must be taken directly from the discriminator.

  • Page 85: Talking S-Meter

    As an example, the diagram below shows connection of a Spectrum Communcations SCR-200 S-meter signal output to the RC-85 controller. The meter should be disconnected and a 10K resistor placed from the signal output to ground. The signal may drive the controller directly. The resistor divides down the S-meter signal to an approximately zero to five volt range and also provides a discharge path for the emitter follower transistor in the receiver’s S-meter...

  • Page 86: Site Alarm

    Remote Control Outputs The RC-85 controller provides three open collector high voltage, high current remote control logic output functions which may be controlled by Touch-Tone commands. The remote control logic outputs may be used for such functions as high/low power select, antenna select, or control of other equipment at the repeater site.

  • Page 87: Expanded Remote Control Outputs

    IC’s required to capture the data. The FC-1 Frequency Control Board is available from ACC for this purpose. One expanded mode shifts the serial data out of two control outputs which function as a serial clock and serial data line.
  • Page 88 RC-85 Repeater Controller Owner’s Manual In the expanded modes, the User Function outputs appear at the shift register outputs, just as they appeared directly at the control outputs in the direct mode. When Control Output 3 is redefined to be the transfer signal, the Link PTT appears at UF 8 in the shifted data stream.
  • Page 89 The format of the BCD frequency data is compatible with the ACC RC-850 Repeater controller (Link 1) and the ITC-32 Intelligent Touch-Tone Control Board. Shown below is circuitry suitable for capturing the serial frequency information for interface to an ICOM IC-22U two meter transceiver as a synthesized remote base.
  • Page 90 RC-85 Repeater Controller Owner’s Manual Kenwood Interface As an alternative to supporting a BCD interface, the controller may connect directly to the serial control port of the Kenwood TS-711A or TS-811A transceivers. With the Kenwood transceivers, users may control frequency, mode, memory recall, and subaudible tone selection.

  • Page 91: Spare Audio Source

    Digital Voice Recorder ACC’s Digital Voice Recorder may interface to the RC-85 controller so that any of the remotely recordable “tracks” may be addressed through the Message Editor. Control signals are passed to the DVR through Control Output 1 as part of the serial data stream supplied at that output in the expanded remote control output mode.

  • Page 92: Sharing The Phone Line

    Phone Line Busy inputs. When a user attempts to bring up the patch, and the phone line is in use by another controller, the RC-85 controller responds by saying “Busy”. The the phone line is not in use, the patch proceeds, and the RC-85 controller pulls the busy output low to indicate to other controllers that the phone line is now in use.
  • Page 93 A block diagram of the RC-85 controller is shown below. The major functional blocks include the microcomputer, audio switching and mixing circuits, buffered I/O, speech synthesizer, tone generator, Touch-Tone decoder, and telephone interface.
  • Page 94 RC-85 Repeater Controller Owner’s Manual The speech synthesizer interfaces to the CPU through I/O ports and is controlled by the microcomputer program. The pot R40 adjustment sets the synthesizer clock frequency, setting the pitch of the voice. The tone generator creates Morse code, courtesy tone, and Touch-Tone audio under control of the computer program.
  • Page 95 No periodic maintenance is necessary to ensure long life. Simply follow common sense in installing the controller, such as avoiding locating it in extremely hot or dirty areas. You should expect your RC-85 controller to run virtually forever.
  • Page 96 RC-85 Repeater Controller Owner’s Manual GENERAL CHECKLIST • ICs firmly seated in sockets? • Cable connectors properly inserted? • +12 volt and 2 grounds connected properly? • DIP switches set correctly and firmly? • Any components hot? (careful!) • Both grounds connected?
  • Page 97 RC-85 Repeater Controller Owner’s Manual RF Interference The controller users relatively high speed digital logic which results in signals with fast edges. The logic signals contain harmonic energy throughout the HF and VHF frequency ranges. Because the controller uses CMOS with somewhat slower edges that TTL or low power Schottky logic, the harmonic energy is lower than it would be in TTL based systems.
  • Page 98 RC-85 Repeater Controller Owner’s Manual Most Often Asked Questions (and Answers) My controller acts erratically. What’s wrong? Be sure that you have connected both grounds to the power supply. The both need to get there. Check for high electrical noise at the site, such as from heavy duty motors or solenoids.
  • Page 99 RC-85 Repeater Controller Owner’s Manual I don’t measure anything on the logic outputs. Why not? The logic outputs are open collector transistors. The transistor is either on, so that there’s a path to ground, or it’s an open circuit. To see a logic voltage level, you need to add a pullup resistor to define the logic high when the transistor is off.
  • Page 100 RC-85 Repeater Controller Owner’s Manual If the Touch-Tone Access Mode is enabled but down, will a reverse patch come through? Yes. A reverse patch will bring up the TT Access Mode and load the TTAM timer. Assuming the timer is non-zero, it will time itself back down if there’s no activity.
